The autosound system is overpriced for what you get, and with today's technology, it is already obsolete. I can put more songs on a mp3 player than a 10 disc changer, and since there are no moving parts, it will never skip. Also the MP3 is smaller than the remote of those hidden systems. I won’t even mention the tacky display they want you to put under the dash.
I have used my iPod and it worked, I image your iTunes cell would also work.
I paid about $425, for it when they first came out, which was still cheaper than Autosound. I think they run about $389 now.
I have had this system in my car for over a year with no problems.
The only regret I have is the loose chrome on my car. I did not realize how loose it was until base from the system kicked in.
I have a 65 GTO, and for those that know the radio bezel has rounded corners. Anything other than original looks out of place in the dash. The MP3 is only noticeable when I take it out from under the seat and place it on the console. I won’t drill any holes to mount it, but that is my preference.
